4.1Safety instructions during operation
zzDo not use the power unit for anything other than its
intended purpose
zzDo not exceed maximum permitted operating pressure
zzEnsure adequate ventilation for heat dissipation
zzDo not mount power unit onto moving parts
zzPower unit and add-on equipment can get hot during
operation - risk of injury!
zzRefer also to HYDAC Operating Instructions and drawing
